Vectra 3D for Dogs

Safe to Use Flea Drop?

Flea drops tend to get a bad rap because a select few of them really are dangerous.

The vast majority of spot-on treatments are as safe as any other pesticide, but the problem is that it’s tough to tell which ones are OK and which ones aren’t.

That’s what we’re here for. We’re investigating each flea drop in order to determine which ones are safe and which ones you should avoid. Today we’re discussing the side effects of Vectra 3D.

Just in case you’re not sure what it is, Vectra 3D is a flea drop for dogs that’s only available by prescription. It claims to kill and repel:

Fleas

Ticks

Mosquitoes

Lice

Fleas

Mites

The active ingredients are dinotefuran, which is a neurotoxin, pyriproxyfen which is an insect growth inhibitor, and permethrin, an insecticide and repellent.

Vectra 3D Side Effects

The most common side effects of Vectra 3D are redness, irritation and/or itching at administration site. This generally goes away within a few hours, and no later than a few days after you apply it.

Some of the less common side effects of Vectra 3D include:

Lethargy

Increased verbalization

Seizures

Drooling

Decreased coordination

Diarrhea

Vomiting

If your dog experiences any of these side effects, you need to wash the Vectra 3D off of him and contact your vet to make sure that there’s nothing seriously wrong.

Though these side effects are rare, they can be life-threatening. Because Vectra 3D is extremely effective and these side effects are so rare, every legitimate website that I could find agreed that the product is safe for use.

For the majority of animals, Vectra 3D is a safe, effective product to use as part of your pest control program but it is a chemical that can hurt your dog if he’s sensitive to the ingredients.

Also, permethrin, one of the three ingredients, is poisonous to cats so you may want to try a different product on your dog if you have a cat.

All things considered, we give Vectra 3D a thumbs up.

If you’ve used Vectra 3D with your dog, please tell us about your experience in the comments section below.

Wheaten terrier had a reaction after use. It’s been 1 and a half days and he still isn’t himself. He won’t eat his treats and is very lethargic. Frontline plus failed to protect him. At a loss for what to try next. If anyone has any ideas please share.

Applied Vectra 3D in the evening and was up all night. He was jerking and twitching and some scratching. Bathed him at 2:30 am AND AGAIN AT 8:30 AM Called Vet and received no help. Told to bath him. Already done. Four days later and still jerking and twitching. Up all night. What to do?

We used vectra on my dog and within five hrs he became very restless and figety he kept pacing. It really concerned us. After an hour or so my husband and I bathed him with an oatmeal shampoo and rinsed him very well. I am very concerned about this product. I will call my vet in the morning.

Had this product applied by a vet yesterday to a 10 year old, 7.5 pound papillion. The little dog
got very red skin , red eyes,and cried all night yesterday & today.
This is a horrible product and should be banned. I just washed him in dawn dish washing liquid and he seems to be calming down a little.

My 7 yr old great Pyrenees had a bad reaction to Vectra3D the day AFTER. She became very very restless, scratched, kept trying to get something off her that WASNT there. Very hot red skin and excessive drooling and heavy panting. I have washed her twice and given her oatmeal rinses. Have her on benedryl maximum dose 3 times a day. Also XANAX to calm her down. Vet said it had to just wear off on its own now. Buyer beware.

My pug has been on vectra 3D for years now and has been doing great on it. I just switched to parastar bcuz they said it was better and the vectra at their office was discontinued and since I put parastar on him he jerks and twitches

I used Vectra on my 12 year old dog a few days ago. (she is an 18 lb Chihuahua/Italian Greyhound mix) She has been vomiting in the evenings but other than that, no different in behavior. I thank God she hasn’t had a more severe reaction to it and will look to find another solution to treat the flea problem. OK vet just said that’s a common side effect and should subside soon. Still will look for another option in the future for treatment of fleas.

Our 14 month old Golden Retriever “Jane”has had her second dose of VECTA. The last time she vomited, we attributed this to a day of swimming…and perhaps ingesting water from diving) off the pier.
This seemed to happen again this month.I do not feel we will not be using it again.
She did not swim this time.

I just applied Vectra to my Chorkie and he started vomiting several hours after I applied it. I was told that it would work really well and that my vet uses it for her dogs. I don’t see anymore fleas on him but I am concerned that he is now vomiting.

I applied Vectra to my Chorkie and it has managed to kill the fleas but now he is vomiting. He has vomited twice now since applying Vectra to him around 4 this evening. Around 9 tonight he vomited twice.
Is this something to be concerned about or is it normal?

Same here. Gave my Min Pin a dose and the next day she started acting strange. It seemed like she was experiencing seizures or hallucinations. It was horrible. I called the vet and she informed me of those reported side effects. I gave her a bath with Dawn dish soap and within a few hours, she was ok. It was a horrifying event. We didn’t know what was wrong with Cookie

I have applied Vectra in the past with no problems to my Bichon until this last application. She became very restless, scratching constantly, no appetite, and her hind legs started with muscle spasms. Bathed her but still scratching and still having hind leg spasms. Will definitely never use this product again. Very dangerous in my opinion.

Put Vectra on my 3 year old Choc. lab. He started vomiting and had diaria. As soon as I started to wash it off he felt better. I would guess the vets get a good kick back from Vectra for recommending it. Front line worked fine but I listened to my vet. STAY AWAY FROM THIS PRODUCT.

The fur is now growing out BROWN where the Vectra 3D was applied to my white 6 year old bichon-poodle mix dog. It looks like chocolate milk was spilled on her back. I called the company who makes Vectra, and the technician told me it is likely permanent! We are bringing her to the vet Monday. So upset!

Vectra 3D killed my Jack Russell. 24 hours after applying it he started having seizures. He was totaling fine, healthy dog. Then 2 seizures 2 hours apart and 3,to one that didn’t stop, vet had to euthanize him. How can these products be out there. I contacted the company and never got a reply! They killed my dog.

This product kills. Put it on my 4 year old dog & she showed no of side effects. My dog just had a we’ll check your twonweeks prior & shevwas healthy. Do not use this product. If it sounds tongood to be true….guesss what it is! This product is dangerous! I will tell everyone to not use this product on their pet. I lost my 4 year old companion & I wouldn’t wish that on my worst enemy! I followed the directions & kill my dog. My heart is breaking. She died less than 24 hours after application!
